TPS2048D

Power Distribution Switches, Load Drivers Overview

The TPS2048D is a quad high-side power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and provides four independent outputs with a continuous current rating of 250 mA per channel. The device features a fixed current limit of 500 mA, an on-resistance maximum of 100 mOhms, and supports active-low enable logic. It includes fault protection mechanisms such as thermal shutdown and under-voltage lockout, functioning within an operating temperature range of 0°C to +85°C in a 16-pin SOIC package.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'D' against official Texas Instruments documentation to confirm pinout compatibility and package dimensions. Ensure the selected variant matches the required thermal performance and electrical ratings for the target application environment before finalizing procurement specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when designing circuits requiring four isolated high-side switches with moderate current capabilities. It is suitable for applications needing built-in fault reporting and protection without external discrete components. Consider the 16-pin SOIC package constraints and thermal dissipation requirements relative to the total load current.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS204xA family of USB power switches from Texas Instruments. It shares functional similarities with other members like the TPS2048A but may differ in specific electrical tolerances or packaging options. The family is designed for robust power distribution in consumer electronics and industrial interfaces.

Power Distribution Switches, Load Drivers Replacement Considerations

Official substitutes include TPS2048AD and TPS2048ADR. Verify that alternative packages maintain identical pin configurations and electrical characteristics to ensure direct interchangeability.
